springmockk | SpringMockK : MockBean and SpyBean , but for MockK | Testing library

After some research I found this issue on the spring-security project, which describes the issue in a more informative way https://github.com/spring-projects/spring-security/issues/9787

There is an open issue in mockk related to the problem. The bug reproduces on a subset of JVM variations. I suppose you have one of such JVM installations locally. As a workaround, you may try to install a different JVM distribution locally. "AdoptOpenJDK: 1.8.0_222 hotspot" seems to be ok according to the link above.

I might be missing something but in that setup, you have to manually run postgreSQLContainer.start() somewhere. As an example it could be done in @BeforeAll.

After read a lot of posible solutions to this problem, i found some workarounds to handle this "issue".

Like i wrote, im using Gson, so, i´ve implemented an overrride for the serialization and another for the deserialization of LocalDates, also i found a hack(?) that override ToString() method in Data class, and more important, i found more issues when i tried to deserialize a post response with nulls in a LocalDate field, also i would like to say (again), that the problem were in the TEST NOT IN PRODUCTIVE CODE, let´s see:

1) Simple Get method, with not nulls

As I mentioned in the comments, the correct way to include subprojects is to replace the path to the subproject with : i.e. if the subproject is in (from the root project) sub/project1, then the correct way to include it is:

Gradle automatically adds build directory in every project (it is normal, every Gradle project has such directories).

If you look in folders of your subprojects (messaging, restapi, etc), you'll probably see similar build folder there. Later you may add more gradle plugins that will store their data in these directories.

IntelliJ IDEA automatically signs these directories as excluded, so IDE does not process any files in them. If you are using Git, add these directories in your .gitignore file (just add "build" line in it, it will remove all build folders for all subprojects from VCS). And if you are VERY annoyed seeing this folders, you can hide excluded folders in IDEA.
